Flat roof venting

[lilman]

I need to vent a 100mm bathroom extractor through a flat roof - can anyone recommend a kit they have used. Also is it fairly straightforward or would I need a roofer to dress the felt/roof covering afterwards? Cheers all

Did one last year builder put pipe in but you will need to put condensation trap on pipe with overflow pipe to outside somehow otherwise you will get condensation and water in fan which will ruin it.

I'm sure Vent-Axia etc. do a kit but I'd definitely get a roofer to do the roof bit.

Concur with the roofer bit...

Its one thing being called back because something electrical has stopped working...

But you don't want to be called back in a couple of years cuz "your roof repair" is now leaking!
